1. GENE AL WA NING
1.1 PLEASE EAD BEFO E USING THIS MANUAL
•This manual is part of the product and should be kept near the instrument for easy and quick reference.
•The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device.
•Check the application limits before proceeding.
1.2 SAFETY P ECAUTIONS
•Check the supply voltage is correct before connecting the instrument.
•Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high
atmospheric humidity to prevent formation of condensation
•Warning: disconnect all electrical connections before any kind of maintenance.
•Fit the probe where it is not accessible by the End User. The instrument must not be opened.
•In case of failure or faulty operation send the instrument back to the distributor or to “Dixell s.r.l.” (see address) with a detailed description of the
fault.
•Consider the maximum current which can be applied to each relay (see Technical Data).
•Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, without crossing or intertwining.
•In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful.
2. GENE AL DESC IPTION
The XLH360 is microprocessor controller, suitable for applications on medium or low temperature refrigerating units. It has 6 output relays to control
compressor, heating elements, defrost/extractor fan, fan, de-humidifier/light and humidifier. It has 2 NTC inputs one for thermostat the other one for
defrost. It’s also present a 4÷20mA input for humidity. There is one digital input (free contact) configurable by parameter. An output allows the user
to program the parameter list with the “Hot Key”.
3. TEMPE ATU E EGULATION
The temperature regulation is performed through neutral zone using compressor and heater output relays.
Set point
OFF
ON
• Heating output: CUT IN is “SET TEM -dbt”, CUT OUT is when the temperature reaches the set point.
• Compressor output CUT IN is “ SET TEM +dbt”, CUT OUT is when the temperature reaches the set point.
3.1 DEF OST
During defrost the temperature control is disabled.
If the second relay is configured as defrost: oA2=dEF then two defrost modes are available through the “tdF” parameter: defrost with electrical
heater (tdF=rE) or hot gas (tdF= in). The defrost interval is control by means of parameter “EdF”: (EdF=in) the defrost is made every “IdF” time,
(EdF=Sd) the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON). At the end of defrost dripping time is
started, set by “Fdt” parameter. To disable the defrost set the MdF parameter to zero
If oA2 is different from dEF, defrost is made only by stopping compressor (tdF=rE).
To disable defrosts set MdF=0.
Humidity regulation during defrost depends on the Hud parameter.
With Hud=no humidity regulation is disabled.
Con Hud=yES humidity regulation is performed also during defrost.
4. HUMIDITY EGULATION
The humidity regulation is performed through neutral zone, by humidifying dehumidifying actions.
Humidity control can be disabled setting the SET % H to “nu” value. In this case only the temperature control is perform.
4.1 HUMIDIFYING ACTION
The humidifying action is done enabling the humidifier relay when the humidity is lower than the “SET %RH-dbH” value.
The relay is switch off when humidity reaches the set values.

4.2 DEHUMIDIFYING ACTION WITHOUT DEHUMIDIFIE ELAY, OA1 DIFFE ENT F OM DEH
In this case the dehumidifying action is performed by setting the following parameters in this way:
tHu = c-H kind of dehumidifying by means of heating and compressor relays
oA1 different from dEH:
The heating and compressor outputs are activated together when humidity is higher than SET %RH+dbH value. Outputs are disabled when humidity
comes back to the SET %RH value.
4.2.1 Relation between cooling, heating and dehumidifying
1. If is simultaneously present a request of cooling (temp>SET TEM +dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has the
priority over the dehumidifying action: only the compressor relay is energised till the SET TEM is reached at this point also the heating relay
is enabled.
2. If is simultaneously present a request of heating (temp< SET TEM -dbt) and dehumidifying (RH > SET %RH+dbH): the dehumidifying action
has the priority over the heating action: both the compressor and the heating relays are energised till the humidity set is reached at this point
only the heating relay is enabled.
4.3 DEHUMIDIFYING ACTION WITH DEHUMIDIFIE ELAY, OA1 = DEH
The configurable relay is used, setting the parameter oA1 =dEH.
NOTE: the LIGHT button is not more available; Two kinds of de-humidifying are available:
4.3.1 Dehumidifying action with ONLY de-humidifier relay
By setting the parameter tHu = db the de-humidifying action is performed by enabling the de-humidifier relay when the humidity is higher than SET
%RH + dbH.
The relay is switch off when humidity comes back to the SET %RH value.
4.3.2 Dehumidifying action with de-humidifier and compressor relays
By setting the parameter tHu = cHu the de-humidifying action is performed by enabling the de-humidifier and compressor relays together. when the
humidity is higher than SET %RH + dbH. The relays are switched off when humidity comes back to the SET %RH value.
If is simultaneously present a request of cooling (temp>SET TEM +dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has the priority
over the dehumidifying action: only the compressor relay is energised till the SET TEM is reached at this point also the de-humidifier is enabled.
5. FA NS
The fan control mode is selected by means of the “FnC” parameter:
FnC=C-n fans will switch ON and OFF with the compressor and not run during defrost:;
FnC= O-n fans will run continuously, but not during defrost
FnC=C-y fans will switch ON and OFF with the compressor and run during defrost;
FnC=O-y fans will run continuously also during defrost
6. EXT ACTO FAN
6.1 EXT ACTO FAN CYCLES
The second relay is configured as extractor fan, oA2= ESt, then it is possible to make extraction cycles, both manually and automatically.
Extraction cycle can be activated both manually by pushing the U key for 3s, and automatically by the internal time rFi. Cycle duration is set by the
rFd parameter. The cycle can be stopped also by key.
If rFI = 0 only manual cycle can be activated.
If rFd = 0 the cycle is stopped only by pushing the key.

10. DIGITAL INPUT
One digital input is present configurable by user by means of the i1F parameter according to the following descriptions.
10.1 DOO SWITCH (I1F = dor)
It signals the door status and the corresponding relay output status through the “odc” parameter: no = normal (any change); Fan = Fan OFF; oFF =
all the loads are switched off.
Since the door is opened, after the delay time set through parameter “dOA”, the alarm output is enabled and the display shows the message “dA”.
The status of loads depends on the “rrd” parameter:
with rrd=no outputs are not affected by the doA alarm;
with rrd=yES = outputs restart with the doA alarm;
The alarm stops as soon as the external digital input is disabled again. During this time and then for the delay “dot” and “doH” after closing the door,
the temperature and humidity alarms are disabled.
10.2 GENE IC ALA M (I1F = EAL)
As soon as the digital input is activated the unit will wait for “did” time delay before signalling the “EAL” alarm message. The outputs status don’t
change. The alarm stops just after the digital input is de-activated.
10.3 SE IOUS ALA M MODE (I1F = BAL)
When the digital input is activated, the unit will wait for “did” delay before signalling the “bAL” alarm message. The relay outputs are switched OFF.
The alarm will stop as soon as the digital input is de-activated.
10.4 P ESSU E SWITCH (I1F = PAL)
If during the interval time set by “did” parameter, the pressure switch has reached the number of activation of the “nPS” parameter, the “PAL”
pressure alarm message will be displayed. The compressor and the regulation are stopped. When the digital input is ON the compressor is always
OFF.
If the nPS activation in the did time is reached, switch off and on the instrument to restart normal regulation.
10.5 HEATING ELAY SAFETY (i1F=Ht)
With i1F=Ht as soon as the digital input is activated for “did” time heating relay is disabled.
The alarm will stop as soon as the digital input is de-activated.
